Dear all, I have a database of 93 variables. I have created a few subsets (10) by inserting different numbers of variables in each one of them (the maximum is 6 anyway), like to represent different phenomena. Hence, this is the logic; 1subset=contains a few variables=expresses 1phenomenon. Now I need to make the regression analysis by considering both Y and X as entire subsets (with different variables inside). I have never did it, and theoretically I feel to say that it is a multivariate regression with more than one explanatory variable. Is there anyone of you who feel like to help me somehow? I would really appreciate it. Even if you need more information to help me, feel free to ask.
